kraal's Introduction

Kraal

Attempting to use GraalVM and Kotlin coroutines together fails due to a limitation of GraalVM - it cannot handle some perfectly valid bytecode produced by the Kotlin compiler.

Kraal performs "node splitting" on Java bytecode in order to eliminate the irreducible loops produced by the Kotlin compiler that GraalVM doesn't handle. The result is a functionally-equivalent bytecode which can be successfully processed with GraalVM.

Eventually, GraalVM may support irreducible loops, or the Kotlin compiler may add a flag to produce bytecode without them. Until then, Kraal allows the usage of these two technologies together.

oracle/graal#366

Usage

Gradle

Using the Kotlin DSL:

plugins {
    id("com.hpe.kraal") version "0.0.15"
}

The Kraal Gradle plugin by default takes all jars produced by the build and their runtime dependencies, processes them to remove irreducible loops, and leaves processed copies of the jars under build/kraal.

The kraal extension is provided for convenient configuration of the default execution of KraalTask:

kraal {
    input = files(...) // *replace* set of input files
    from(...)          // or, *add* to set of input files

    outputDirectory = file(...)
}

The task and extension expose properties that create a Provider of a zipTree of the processed versions of all of the files. This can be used as a convenient way to create a "fat jar" of the processed classes:

val fatjar by tasks.creating(Jar::class) {
    from(kraal.outputZipTrees) {
        exclude("META-INF/*.SF")
        exclude("META-INF/*.DSA")
        exclude("META-INF/*.RSA")
    }
}

See the example directory for a complete working example with Ktor and GraalVM.

Maven

Use the exec-maven-plugin to execute the Kraal driver application com.hpe.kraal.MainKt:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.6.0</version>
    <dependencies>
        <dependency>
            <groupId>com.hpe.kraal</groupId>
            <artifactId>kraal</artifactId>
            <version>0.0.15</version>
        </dependency>
    </dependencies>
    <executions>
        <execution>
            <goals>
                <goal>java</goal>
            </goals>
            <phase>package</phase>
            <configuration>
                <mainClass>com.hpe.kraal.MainKt</mainClass>
                <arguments>
                    <argument>${project.build.directory}/${project.build.finalName}.${project.packaging}</argument>
                </arguments>
                <includePluginDependencies>true</includePluginDependencies>
            </configuration>
        </execution>
    </executions>
</plugin>

kraal's Issues

Getting Error at instruction 115: Incompatible stack heights when trying to run Kraal

Thanks for publishing this useful tool. I'm trying to get native image generation for jars generated by Ballerina language. When I'm testing, I could generate a simple jar file and run it with Ballerina. Also I can use GraalVM to generate a native image out of it. When I try to run kraal on the same jar, I'm seeing following exception.

The file in question ballerina/io/WritableTextRecordChannel.class contains standard IO routines in Ballerina language. Byte code generation in Ballerina is done through ASM lib as well.

javap -c -p -v output for the class can be found here. There the instruction 115 seems to be an aastore. May be I'm looking at the wrong place. Appreciate any tips for debugging this. Thanks.

Could not create an instance of type com.hpe.kraal.gradle.KraalExtension_Decorated.

Hi there, after giving up on trying ktor with graal I found this, and I was so happy to see someone is looking into this.

But I could not manage to get the simplest gradle (groovy not kotlin) project started.

I get the following error when trying to build the project:

Any ideas?

Issue with gradle and maven examples

Hi,

I'm trying to run gradle and maven examples and I'm getting an exception

Thank you,

Steps Maven:

mvn install
native-image --static --report-unsupported-elements-at-runtime -jar target/maven-example.jar = ok
./maven-example = exception

GraalVM complains with the error "stacks do not match on merge; bytecodes would not verify" error after running through Kraal

I have a program with a dependent jar that has non-reducible loops. The program I'm running can also have non-reducible loops. Here I'm running the program through Kraal before native image. Native image generator detect the dependency with a non-reducible loop and throws out following error.
